calibration
Check:
The position sensor (Hall-effect sensor) connector and cable. .
See Figure 5-1 and find the connector J6 for local or remote
sensor connection for the ICoT 5400. See
• Figure 6-3 and find the connectors J3 and J4 for remote
sensor connection for the ICoT 6400. The connector J2 is
used for local sensor connection for the ICoT 6400.
• Magnet assembly:
o For rotary magnets check if it is not rotated 90
degrees
o
For linear magnets, check if the magnet assembly
center is matching the actuator mid position.
• Pressure supply stability.
• Actuator and tubing leaks.
• Manifold and transducer assembly are tightly coupled to
the enclosure and there are no leaks.
• Check if the cable between the inner canister and the
pneumatic transducer assembly is tightly connected.
• Actuator/Valve assembly integrity.
• Try to repeat a full auto CAL.
• Call Westlock- for additional support.

Check:
The position sensor (Hall-effect sensor) connector and cable. .
See Figure 5-1 and find the connector J6 for local or remote

•
Figure 6-3 and find the connectors J3 and J4 for remote
sensor connection for the ICoT 6400. The connector J2 is
used for local sensor connection for the ICoT 6400.
• Magnet assembly is in correct position:
o For rotary magnets check if it is not rotated 90
degrees
o For linear magnets, check if the magnet assembly
center is matching the actuator mid position.
Check if the proper fail-down or fail-up magnet is
being used
• Try to repeat a full auto CAL
• Try to replace the Position Sensor and/or the magnet
• Remove power for at least 1 minute and retry
• Remove power for at least 1 minute, perform a factory
default initialization (see Section 9.2.2.4) and retry a full
auto CAL
• Call Westlock- for additional support.
